I have just finished my first round of testing on thrall drop rates. I have summoned, at least once, every ‘most powerful surge.’ Here’s what they summon:
Focus Altar - South = Yoggites (Darfari) and ostrich chicks
Focus Altar - Center = Jhebbal Sag (Desert Dogs) and Locust spawn pets (some Spider Eggs, too)
Focus Altar - East = Cultists (Lemurian) and no pets
Focus Altar - West = Relic Hunters (treasure seekers) and elephants/camels
Focus Altar - North = Aesir and sabertooth kittens
Focus Altar - Northeast = Aquilonian and gators
At this time, I have collected 10 T4 archers, 10 T4 fighters, over 100 pets (largely due to the locust overspawn bug, but still, lots of them), 10 T4 performers (entertainers), 5 T4 priests, but not one – yes, that’s right – not one T4 crafting thrall. No T4 carpenters, blacksmiths, alchemists, smelters, armorers, tanners, or cooks. Not one.
Now there have been some T3s, T2s, and T1s as crafters – but no T4. And that’s out of six “most powerful surges” with each having seven waves of thralls dropping on three separate platforms.
I would HIGHLY recommend increasing the chances for T4 crafter thrall drops, increasing the number of crafting thrall drops in general, and slightly decreasing some of the fighter/archer thrall drops. And if this is a PvE vs PvP issue, then make PvP servers drop more fighter/archer thralls and PvE servers drop more crafting thralls (with PvE-C the balance in the middle) – with an admin slider option as to how to set surge thrall drop rates.
